It Just Didn't Know What I Lifted.](https://lukeboyle.com/blog/enriching-garmin-strength-workouts-from-strong/) _2026-06-25 · Boyleing Point_ My watch logs a strength session's heart rate and the timing of every set, then leaves the exercise, reps and weight blank. Strong has all of that and no way to send it over. So I wired them together — editing the Garmin activity in place, no duplicate, heart rate untouched. ## [Biotronik performs first US implant of LivIQ leadless pacemaker](https://www.implantable-device.com/2026/06/15/biotronik-performs-first-us-implant-of-liviq-leadless-pacemaker/) _2026-06-15 · David Prutchi · The World of Implantable Devices_ On June 8, 2026, Biotronik announced the first U.S. implant of its LivIQ leadless pacemaker as part of the BIO-LivIQ global pivotal clinical trial.
